Health Inequalities Among Older Adults In Vietnam: Evidence From The 2011 Vietnam National Aging Survey, Bussarawan Teerawichitchainan, Thanh Long Giang

Research Collection School of Social Sciences

Vietnam’s economic development, change in health infrastructure, demographic and epidemiological transitions, and projected rapid population aging point to the need for understanding issues related to the wellbeing of older adults. Few recent studies that examine old-age health among specific Vietnamese populations notwithstanding, a national profile of older adults’ health, particularly health inequalities among the aged, is still lacking for Vietnam. To address this gap, we analyze nationally representative data from Vietnam’s first national survey of older adults to examine socioeconomic gradients in health at older ages in urban and rural Vietnam. Our specific research questions include: how are various measures …

Southeast Asia: Sources Of Regime Support, Alex Chang, Yun-Han Chu, Bridget Welsh

Research Collection School of Social Sciences

The authors’ empirical analysis shows both commonalities and variations in the sources of regime support in Southeast Asian countries. Most regimes in the region draw political legitimacy from perceptions that their governance is effective and marked by integrity. These findings lend support to the argument that regime legitimacy—when it is won and when it is lost—is rooted in the output side of the political system. Yet delivering economic prosperity alone will not suffice. In order for political regimes in Southeast Asia to win over their people, they must control corruption, respect the rule of law, treat all citizens fairly and …

Positive Affect Improves Working Memory: Implications For Controlled Cognitive Processing, Hwajin Yang, Sujin Yang, Alice M. Isen

Research Collection School of Social Sciences

This study examined the effects of positive affect on working memory (WM) and short-term memory (STM). Given that WM involves both storage and controlled processing and that STM primarily involves storage processing, we hypothesised that if positive affect facilitates controlled processing, it should improve WM more than STM. The results demonstrated that positive affect, compared with neutral affect, significantly enhanced WM, as measured by the operation span task. The influence of positive affect on STM, however, was weaker. These results suggest that positive affect enhances WM, a task that involves controlled processing, not just storage processing. Additional analyses of recall …

Misrepresentation, Fiduciary Duty And Negligence: Investor Scores Rare Win In Deutsche Bank V Chang, Kee Yang Low

Research Collection Yong Pung How School Of Law

Law reports of the last decade are littered with unsuccessful suits by investors against their banks for negligent or unsuitable advice. Rarely do investors succeed. This is despite the wide array of courses of action available, allowing them to sue for breaches by the bank of contractual duty (in particular, through misrepresentation), duty of care, statutory duty and fiduciary duty.

Local Linear Gmm Estimation Of Functional Coefficient Iv Models With Application To The Estimation Of Rate Of Return To Schooling, Liangjun Su, Irina Murtazashvili, Aman Ullah

Research Collection School Of Economics

We consider the local linear GMM estimation of functional coe cient models with a mix of discrete and continuous data and in the presence of endogenous regressors. We establish the asymptotic normality of the estimator and derive the optimal instrumental variable that minimizes the asymptotic variance-covariance matrix among the class of all local linear GMM estimators. Data-dependent bandwidth sequences are also allowed for. We propose a nonparametric test for the constancy of the functional coefficients, study its asymptotic properties under the null hypothesis as well as a sequence of local alternatives and global alternatives, and propose a bootstrap version for …

Nonparametric Testing For Asymmetric Information, Liangjun Su, Martin Spindler

Research Collection School Of Economics

Asymmetric information is an important phenomenon in many markets and in particular in insurance markets. Testing for asymmetric information has become a very important issue in the literature in the last two decades. Almost all testing procedures that are used in empirical studies are parametric, which may yield misleading conclusions in the case of misspecification of either functional or distributional relationships among the variables of interest. Motivated by the literature on testing conditional independence, we propose a new nonparametric test for asymmetric information, which is applicable in a variety of situations. We demonstrate that the test works reasonably well through …

Testing Monotonicity In Unobservables With Panel Data, Liangjun Su, Stefan Hoderlein, Halbert White

Research Collection School Of Economics

Monotonicity in a scalar unobservable is a crucial identifying assumption for an important class of nonparametric structural models accommodating unobserved heterogeneity. Tests for this monotonicity have previously been unavailable. This paper proposes and analyzes tests for scalar monotonicity using panel data for structures with and without time-varying unobservables, either partially or fully nonseparable between observables and unobservables. Our nonparametric tests are computationally straightforward, have well behaved limiting distributions under the null, are consistent against precisely specified alternatives, and have standard local power properties. We provide straightforward bootstrap methods for inference. Some Monte Carlo experiments show that, for empirically relevant sample …

Impact Of Food Inflation On Poverty In The Philippines, Tomoki Fujii

Research Collection School Of Economics

We simulate the impact of food inflation between June 2006 and June 2008 on poverty across different areas and between agricultural and non-agricultural households. We explicitly treat the spatial heterogeneity in food inflation and the differences in consumption and production patterns across households by merging household expenditure survey and price datasets at the provincial level or lower. Although some of the poor agricultural households may have escaped poverty, the poorest of the poor, whether they are in an agricultural household or not, are severely and adversely affected by the food inflation.

Collusion Set Detection Using A Quasi Hidden Markov Model, Zhengxiao Wu, Xiaoyu Wu

Research Collection School Of Economics

In stock market, a collusion set is defined as a group of individuals or organizations who act cooperatively with an intention of manipulating security price. Collusion-based malpractices impose large costs on the economy, but few techniques have yet been developed for collusion set detection. In this article, we propose a quasi hidden Markov model (QHMM) approach. In particular, we consider the transactions as a marked point process with hidden states, and we calculate the class conditional probabilities to identify the malicious transactions. The detection algorithms associated with the model are recursive, hence suitable for online monitoring and detection. The QHMM …

Social Capital, Informal Governance, And Post-Ipo Firm Performance: A Study Of Chinese Entrepreneurial Firms, Jerry X. Cao, Yuan Ding, Hua Zhang

Research Collection Lee Kong Chian School Of Business

This paper explores the links between entrepreneurs' social capital and post-IPO firm performance in China's unique capital market and regulatory setting. Using hand-collected data on entrepreneurs' political connections and firm financial information, we construct original measures for various types of social capital and examine their roles in determining the accounting and financial performance of entrepreneurial firms after an IPO. On one hand, firm accounting performance is enhanced by entrepreneurs' bridging social capital, such as political connections or a willingness to share power with external investors. On the other hand, bonding social capital such as intra-group related party transactions causes performance …

The Transformation Of Urban Vegetable Retail In China: Wet Markets, Supermarkets, And Informal Markets In Shanghai, Qian Forrest Zhang, Zi Pan

Research Collection School of Social Sciences

The state-monopolised system of vegetable retail in socialist urban China has transformed into a market-based system run by profit-driven actors. Publicly owned wet markets not only declined in number after the state relegated its construction to market forces, but were also thoroughly privatised, becoming venues of capital accumulation for the market operators now controlling these properties. Self-employed migrant families replaced salaried state employees in the labour force. Governments’ increased control over urban public space reduced the room for informal markets, exacerbating the scarcity of vegetable retail space. Fragmentation in the production and wholesale systems restricted modern supermarkets’ ability to establish …

A Smooth Test For The Equality Of Distributions, Anil Bera, Aurobindo Ghosh, Zhijie Xiao

Research Collection School Of Economics

The two-sample version of the celebrated Pearson goodness-of-fit problem has been a topic of extensive research, and several tests like the Kolmogorov-Smirnov and Cramer-von Mises have been suggested. Although these tests perform fairly well ´ as omnibus tests for comparing two probability density functions (PDFs), they may have poor power against specific departures such as in location, scale, skewness, and kurtosis. We propose a new test for the equality of two PDFs based on a modified version of the Neyman smooth test using empirical distribution functions minimizing size distortion in finite samples. The suggested test can detect the specific directions …

Finding The Optimal Social Trust Path For The Selection Of Trustworthy Service Providers In Complex Social Networks, Guanfeng Liu, Yan Wang, Mehmet A. Orgun, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Online social networks have provided the infrastructure for a number of emerging applications in recent years, e.g., for the recommendation of service providers or the recommendation of files as services. In these applications, trust is one of the most important factors in decision making by a service consumer, requiring the evaluation of the trustworthiness of a service provider along the social trust paths from a service consumer to the service provider. However, there are usually many social trust paths between two participants who are unknown to one another. In addition, some social information, such as social relationships between participants and …

Penchant For Property Drives Buoyant Market, Singapore Management University

Perspectives@SMU

The catch phrase “location, location, location” is often cited by the real estate industry as crucial to closing a deal. In the case of land-scarce Singapore, its citizens’ penchant for property is giving Mr Patrick Liew, CEO of real estate company HSR Property Group, much cause for optimism as he says he is “very excited” at the opportunities available in the robust property market.

Presidential Pardon In Singapore: A Comment On Yong Vui Kong V Ag, Shubhankar Dam

Research Collection Yong Pung How School Of Law

This paper critically analyses the decision of the Singapore Court of Appeal in Yong Vui Kong v Attorney-General in relation to presidential pardon. Two questions were central to the case. First, is the President bound by the decision of the Cabinet in pardon-related matters? Secondly, are decisions regarding pardon—whether made by the Cabinet or President—subject to judicial review? In relation to the first question, the Court based its reasoning on Singapore's political system being a Westminster-inspired model and, therefore, that the President generally undertakes the same functions as the British monarch. However, this paper identifies the unique features of Singapore's …

China’S Agrarian Reform And The Privatization Of Land: A Contrarian View, Qian Forrest Zhang, John A. Donaldson

Research Collection School of Social Sciences

Many media and scholars outside China are advocating for the privatization of land ownership in China, claiming it to be a necessary step before China can transform its agriculture into large-scale, market-oriented and technology-intensive modern agriculture. Chinese scholars advocating land privatization, on the other hand, typically argue that land privatization would offer farmers more protection of their rights. In this paper, we present a contrarian view to these calls for land privatization published in both mainstream media and academic journals. We argue that, under China’s current system of collective land ownership and individualized land use rights, the aforementioned goals can …

Global Companies And Global Society: The Evolving Social Contract, Ann Florini

Research Collection School of Social Sciences

Globalization, privatization, and CHANging ideas about the roles of business and government are transforming the social contract under which business is allowed to operate. Global companies are also policy-makers and public goods providers, governments seek profits through state-owned enterprises and sovereign wealth funds, and everyone is trying to figure out how to partner with everyone else. As a result of global economic and social integration, more and more of the business-society interaction has played out at a transnational rather than purely national level, involving transnational corporations, transnational civil society networks and organizations, and inter-governmental organizations. Experiments with codes of conduct, …

Social Relations, Health Behaviors, And Health Outcomes: A Survey And Synthesis, Louis Tay, Kenneth Tan, Ed Diener, Elizabeth Gonzalez

Research Collection School of Social Sciences

The primary goal of this paper is to summarise current evidence on social relations and health, specifically how social integration and social support are related to health behaviors and health outcomes, using results from published reviews. Our analysis revealed that social relations are beneficial for health behaviors such as chronic illness self-management and decreased suicidal tendency. The salutary effects of general measures of social relations (e.g. being validated, being cared for, etc.) on health behaviors (e.g. healthy diet, physical activity, smoking, alcohol abuse) are weaker, but specific measures of social relations targeting corresponding health behaviors are more predictive. There is …

The 2012 Amendments To Singapore's Evidence Act: More Questions Than Answers As Regards Expert Opionion Evidence?, Siyuan Chen

Research Collection Yong Pung How School Of Law

Singapore amended the expert opinion evidence provisions in its Evidence Act (EA) in 2012. The criteria for admissibility have been broadened, but the courts are now also expressly given the discretion to exclude relevant expert opinion evidence if it is ‘in the interests of justice’. This article explains why the 2012 amendments have raised more questions than answered them. First, Parliament did not appear to have properly appreciated the distinction—as conceptualised by the EA—between legal and logical relevance and relevance and admissibility. Second, it did not appear to have appreciated the distinction between general and specific relevance. Third, the introduction …

Faith, Freedom, And Us Foreign Policy: Avoiding The Proverbial Clash Of Civilizations In East And Southeast Asia, Eugene K. B. Tan

Research Collection Yong Pung How School Of Law

In the immediate aftermath of 9/11, the primary weakness of US foreign policy, particularly in Southeast Asia which is home to the largest Muslim community in the world, was that it was driven by concerns over archipelagic Southeast Asia as the “second front” in the “global war against terror.” Military warfare and coercive legislation and enforcement are grossly inadequate in winning the hearts and minds of a community. Religion-wise, Asia is not a tabula rosa. Many religions have long co-existed in Asia. The virtues of religious freedom are not alien to Asia but need nurturing given the dominant imperatives of …

Reassessing Apec's Role As A Trans-Regional Economic Architecture: Legal And Policy Dimensions, Pasha L. Hsieh

Research Collection Yong Pung How School Of Law

This article examines the two-decade evolution of the Asia-Pacific Economic Cooperation (APEC) and the future prospects for Asian regionalism. It argues that while APEC retains advantages over competing regional structures, it should undergo reforms to accelerate the Bogor Goals and ensure its complementarity with the World Trade Organization (WTO). The article first analyzes the impact of stake-holding countries’ trade policies on APEC’s structure and development. By assessing APEC’s soft-law mechanism, it explores APEC’s WTO-plus contributions that reinvigorated the International Technology Agreement negotiations and improved supply chain facilitation. APEC’s goal of creating a Free Trade Area of the Asia-Pacific (FTAAP) can …

The Undercommons: Fugitive Planning And Black Study, Stefano Harney, Fred Moten

Research Collection Lee Kong Chian School Of Business

In this series of essays, Fred Moten and Stefano Harney draw on the theory and practice of the black radical tradition as it supports, inspires, and extends contemporary social and political thought and aesthetic critique. Today the general wealth of social life finds itself confronted by mutations in the mechanisms of control: the proliferation of capitalist logistics, governance by credit, and the management of pedagogy. Working from and within the social poesis of life in THE UNDERCOMMONS, Moten and Harney develop and expand an array of concepts: study, debt, surround, planning, and the shipped. On the fugitive path of an …

Situation Assessment As An Ignored Factor In The Behavioral Consistency Paradigm Underlying The Validity Of Personnel Selection Procedures, Anne Jansen, Klaus G. Melchers, Filip Lievens, Martin Kleinmann, Michael Brandli, Laura Fraefel, Cornelius J. Konig

Research Collection Lee Kong Chian School Of Business

This study contributes to the literature on why selection procedures that are based on the behavioral consistency logic (e. g., structured interviews and assessment centers) are valid predictors of job performance. We rely on interactionist theories to propose that individual differences in assessing situational demands explain true variance in performance in selection procedures and on the job. Results from 124 individuals in a simulated selection process showed that the assessment of situational demands was related to both selection and job performance. Individual differences in assessing situational demands also contributed to the criterion-related validity of assessment center and structured interview ratings, …

Prosecutorial Discretion And The Legal Limits In Singapore, Gary Kok Yew Chan

Research Collection Yong Pung How School Of Law

Article 35(8) of the Constitution of the Republic of Singapore states that the Attorney-General, as the Public Prosecutor, “shall have the power, exercisable at his discretion, to institute, conduct or discontinue any proceedings for any offence”. This prosecutorial discretion, though extremely wide, is not an unfettered one and must not be exercised in bad faith or in breach of constitutional rights. With respect to the equality provision in the Constitution, the Prosecution has to give unbiased consideration to all potential accused persons and avoid any irrelevant considerations. The article considers whether the presumption of the constitutionality of prosecutorial decisions and …
